L lNOTYPE-MACHINE.

SPECIFICATION forming part of Letters Patent No. 730,734, dated June 9, 1903.

Application filed March 28, 1903. Serial No. 149,921. (No model.)

To all whmn it may concern:

Be it known that I, GEORGE A. BATES, of Brooklyn,county of Kings, and State of New York, have invented a new and useful Improvement in Linotype-Machines, of which the following is a specification.

My invention has reference to linotype-machines in which the slug or linotype is driven out of the mold between trimming-knives and intoa receiving-galley beyond them by the end of a reciprocating ejector-blade-as shown, for example, in United States Letters Patent No. 436,531. This blade requires to be projected a long distance beyond its guides and when made very thin to eject the thin slugs frequently demanded for special purposes. It is liable to bend or buckle under the se Vere end pressure to which it is subjected in starting the slug from the mold. V

The object of my invention is to guide or support these thin blades; and to this end it consists in the employment of one or more guiding or supporting bars arranged adjacent to the blade, as hereinafter described.

WVith the exception of the guide-bars and the parts immediately associated therewith the machine may be in all respects of ordinary construction, and I have'therefore limited the drawings to such portions of the machine as are necessary to an understanding of the invention.

Referring to the drawings, Figure 1 represents a horizontal section through the moldtrimming knives, receiving-galley, ejector, and attendant parts of the machine with my improvement incorporated therein, the ejector-blade standing in its normal or retracted position. Fig. 2 is a similar view showing the blade in its forward position in the act of delivering a slug to the galley. Fig. 3 is an elevation of the ejector-slide-and blade, together with the ordinary guide and the special supports for the blade. Fig. 4. is a vertical cross-section on the line 4 4, Figs. 1 and 3. Fig. 5 is a vertical cross-section on the line 5 5, Figs. 1, 2, and 3. Fig. 6 is a perspective view of the rear end of the ejectorblade.

Referring to the drawings, A represents the frame of the machine; 13, the verticallyrevolving mold-wheel, having one or more slotted molds 0 fixed therein, so that by the rotation of the wheel each mold may be brought first to a horizontal position at its top that the slug may be 'cast therein and afterward brought to a vertical position at one side, as shown in the drawings, preparatory to the delivery of the slug or linotype therefrom.

D D represent two upright knives fixed on the frame forward of the mold, so that the outgoing slug will be directed between these knives and trimmed to the proper thickness.

'E represents the slug-receiving galley at the front of the machine, and F an upright yielding plate cooperating with an opposed vertical surface of the frame to guide the outgoing slugs from the knives to the galley.

G represents the horizontally-reciprocating ejector-blade attached to the forward end of its operating-slide H. This ejector-slide is mounted and guided, as usual, in the side face of a second slide I, mounted in the main frame and carrying a lateral arm which supports the mold-Wheel; During the casting of a'slug and until the mold has been turned 'to the position shown in Figs. 1 and 2 the ejector-blade stands in the retracted position. (Shown in Fig. 1.) While the mold is at rest the blade advances endwise to the position shown in-Fig. 2, driving the slug before it out of the mold, between the knives, and through the intermediate guide to the galley.

In the machine as heretofore constructed the front end of the ejector-blade has been supported and guided on one side by the continuous surface of the mold-slide I. On the opposite side it has been guided only at the forward end by a yielding pressure-plate K, seated in the frame and urged forward by springs L. The slug sometimes adheres strongly to the mold and ofiers untilit is started a great resistance -to the advance of the ejector-blade, The'parts so far described are of ordinary construction. The ejector-blade being under the old construction unsupported on one side between the front guide K and the forward end of the slide H would spring or bend away from the slide I. It is to overcomev this evil that the present improvement is designed. I provide for the purpose one or more horizontal stationary supporting-bars IOO M. They lie against the vertical outer face of the ejector-blade, being secured at their forward ends to the frame adjacent to the pressure device K and seated at their rear ends in horizontal grooves cut for the pun pose in the face of the ejector-slide H. There may be one, two, or more of these bars M, according to the width of the ejector-blade, one above another, as shown in Figs. 3 and 4. Their forward ends are preferably seated in notches in the frame and secured thereto by pins N. It will be observed that under this arrangement of parts the ejector-blade lies between the slide I on one side and the bars M on the other, so that it is supported and guided on both sides while being driven forward by the slide H. As it is desirable to extend the bars M forward as near to the mold as possible, they are carried across the inner face of the yielding guide-bar K, which is grooved or recessed across its face for the passage of the guide-bars, as shown in Fig. 5. I prefer to connect the rear endof the ejectorblade detachablyto its operating-slide by fastening-pins O and springs, as shown in the drawings,'this construction being identical with that represented in United States Letters Patent No. 560,537. In order that the thin blade may be firmly held by the fastening-pins, I reinforce its rear end by riveting plates g to its face, as shown in Fig. 6. The spaces between these reinforcing-plates will be such as to permit the passage of the guidebars M.

The essence of myinvention resides in combining with the ejector-blade longitudinal guides or supports arranged to prevent the buckling of the blade during its advance against the slug without interfering with the advance of the blade or its operating-slide.

It will be manifest to the skilled mechanic that the details may be widely modified without passing beyond the limits of my invention.

Having thus described myinvention, what I claim is 1. In a linotype-machine and in combination with the mold, the ejector-slide, fixed guides between which the slide advances, and a blade-operating slide recessed for the pas- 5o sage of the guides on one side of the slide.

2. In a linotype-machine, the combination of the ejector-blade, its operating-slide, the guide I, located on one side of the blade, and a fixed guide M, located on the opposite side of the blade and extending loosely into the operating-slide.

3. In alinotype-machine, the ejector-blade,

a guide I, on one side of the same, a fixed guide M, on the opposite side of the same, and a yielding pressure device K, recessed for the passage of the guide M. r

4. In a linotype-machine, the combination of an ejector-blade, a fixed guide on one side of the same, one or more longitudinal fixed guides on the opposite side of the same, and the blade-operating slide recessed to admit the last-named guides.

5. In a linotype-machine, longitudinal stationary guides, an ejectorblade having its side face seated against said guides, and a blade-operating slide recessed to admit the guides as it advances the blade along them.

6. In a linotype-machine, the combination of a mold, a reciprocating ejector-blade ar- 7 ranged to pass at its forward end through the mold, guides extending along opposite sides of the blade from points near the mold to the rear end of the blade and means for advancing the blade between said guides.

In testimony whereof I hereunto set my hand, this 19th day of February, 1903, in the presence of two attesting witnesses.

GEORGE A. BATES.
